CONTROL OF FIELD DEVICE ON LOW POWER WIRELESS NETWORKS

摘要

A control system uses a wireless network to provide communication between a host computer and field devices. The host and the field devices communica te with one another using control messages and response messages based upon a known control system protocol. The control and response messages are embed ded as a payload within a wireless message that is transmitted over the wire less network. When the wireless message is received at its ultimate destinat ion, the control or response message is separated from the wireless message and is delivered to the intended recipient (either a field device or the hos t computer).
